1.What is Ohm?

A: ohm is the resistance. The heating wire is heated by the resistance

Under the same length and same voltage, the higher the resistance, the smaller the power and the lower the heat output.

Under the same length and same voltage, the smaller the resistance, the greater the power and the greater the heat output.

2.How to calculate power

Power = voltage * voltage / (resistance length)

For example:

Using a 5ml / M 12V cable, the power supply is:

12 V * 12 V / 2 m * 5 ohm = 14.4 w

Use a 15m cable of 1.4ml in 24 volt range

24 V * 24 V / 15 m * 1.4 ohm = 27.4 w

Note to Buyer:

1: it is recommended that the power per meter of the theoretical heating line should not be higher than 20W, because if the power per meter is about 20W, long-term heating may damage the surface layer of the heating line. If the power is greater than 20W per meter, temperature control is required

2: when using, the lines and lines cannot overlap and cross

3.what is the power of the cable? What’s the temperature?

A: 1. The power of the cable is based on the length you use. You can calculate the power according to the above example.

Power = 5 W / m, temperature is about 30 ~ 40 ℃;

Power = 10 W / m, temperature is about 40 ~ 50 ℃;

Power = 15 W / m, temperature is about 50 ~ 60 ℃;

Power = 20 W / m, temperature about 60 ~ 70 ℃;

Please note that this is a reference, which is not entirely correct because of the different test conditions.
